In short, the CAP theorem is a mathematical theorem describing how our application will behave in the event of network partitioning. It is one of the most important laws currently in existence. Through the course of this text, I will share more information on this theorem and why it is important. By the time you’re done reading, you’ll also know why CAP may not be enough for modern-day systems.
Before we start, because the CAP theorem is inseparably related to distributed systems, I would like to add a quick word about them.
